Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel tableware processing, and in particular relates to a method for processing stainless steel tableware. Background Art

[0002] At present, the polishing process of stainless steel tableware such as knives, forks and spoons mainly relies on manual polishing machines or automatic polishing machines. The standardized process is usually divided into three stages: first, a coarse-grained polishing wheel is used with polishing paste to remove burrs and surface unevenness, then a medium-grained polishing wheel is used to further smooth the surface, and finally a fine-grained polishing wheel is used to achieve a mirror effect. This method is more efficient in mass production of standard tableware, but when faced with high-end customized tableware, such as carved fork handles, curved spoon bodies, and special-shaped knives, the mechanical structure defects of traditional manual polishing machines or automatic polishing machines gradually become apparent.

[0003] The mechanical structure of traditional automatic polishing equipment is usually designed for fixed-axis rotation or linear reciprocating motion, which limits the motion trajectory of the polishing head and makes it difficult to evenly cover the depressions, edges and fine lines of complex geometric shapes, resulting in inconsistent surface gloss after polishing, blurred details, and even damage to fine structures due to local over-polishing. In addition, manual polishing machines require frequent manual intervention, such as manual angle adjustment or rework, which is not only inefficient but also increases production costs and quality fluctuation risks. In response to the above problems, the inventors have proposed a new processing method for stainless steel tableware, which can polish the surfaces of stainless steel tableware such as knives, forks and spoons at multiple angles, and adapt to the multi-directional polishing requirements of complex surfaces such as high-end customized knives, forks and spoons through a multi-degree-of-freedom motion polishing head, thereby improving processing accuracy while reducing dependence on manual experience. This technical improvement is of great significance to meeting the high quality requirements and complex design trends of high-end customized tableware. Summary of the invention

[0030] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following will describe in detail the specific embodiments, structures, features and their effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0031] Please refer to Figure 1 - Figure 5 , this embodiment provides a processing method for stainless steel tableware, including the following steps:

[0032] S1: Pretreatment, fixing the stainless steel tableware of knives, forks and spoons to the fixture, removing the oil stains and impurities on the surface of the stainless steel tableware of knives, forks and spoons by ultrasonic cleaning, and performing pickling or sandblasting treatment to remove the oxide layer;

[0033] S2: Rough polishing, using a coarse-grained polishing wheel in combination with polishing paste, and performing multi-angle rough polishing on the surface of the tableware through a multi-degree-of-freedom polishing device to remove burrs and surface unevenness; in addition, in actual operation, it also involves system control. It is necessary to generate multi-axis linkage trajectories based on the three-dimensional models of knives, forks and spoons respectively, drive the polishing head 9 along the preset path for multi-angle coverage through the numerical control system, and real-time feedback position data to correct trajectory deviations; control the movement of the polishing head 9 through the servo motor and harmonic reducer to ensure uniform grinding of depressions and edges;

[0034] S3: Medium polishing, replacing the medium-grained polishing wheel, dynamically adjusting the polishing angle and pressure through a multi-degree-of-freedom polishing device to smooth the surface of the tableware; in addition, in terms of system control, it is necessary to integrate a pressure sensor and an angle encoder, collect contact pressure and angle information in real time through a closed-loop control algorithm, adaptively adjust the downward pressure and inclination angle of the polishing head 9, and also need to use a PID controller to dynamically match the surface curvature change to avoid local overpressure or under-polishing;

[0035] S4: Fine polishing, using a fine-grained polishing wheel, and moving along the complex curved surface trajectories of knives, forks and spoons through a multi-degree-of-freedom polishing device to achieve a mirror effect; in addition, in terms of system control, generate curved surface trajectories based on high-precision model data, and achieve continuous path planning through interpolation algorithms to ensure consistent mirror effects;

[0036] S5: Post-treatment, cleaning the polishing residues, wiping the surface with alcohol, and using an instrument to detect the glossiness and flatness. Among them, the polishing head 9 of the multi-degree-of-freedom polishing equipment realizes full-coverage polishing of complex geometric shapes through multi-axis coordinated control and an adaptive algorithm, and the process parameters between each step are seamlessly connected through the central control system.

[0037] Currently, in the polishing process of stainless steel tableware such as knives, forks, and spoons, due to the mechanical structure limitations of traditional manual and automatic polishing machines, it is difficult to meet the polishing requirements of the complex curved surfaces and fine structures of high-end customized tableware, resulting in uneven surface glossiness and quality fluctuations. To solve this problem, in one embodiment, this solution uses a multi-degree-of-freedom polishing equipment to achieve multi-angle polishing of the surface of stainless steel tableware, avoiding uneven polishing caused by manual adjustment, improving the processing quality of stainless steel tableware, enhancing the surface glossiness of stainless steel tableware, and combining a high-precision three-dimensional model and an adaptive algorithm to achieve efficient and uniform polishing of the complex curved surfaces and fine structures of stainless steel tableware such as knives, forks, and spoons. By precisely controlling the multi-axis linkage trajectory, pressure, and angle of the polishing head 9, and dynamically adjusting the polishing process parameters, the problems of uneven surface glossiness and quality fluctuations caused by mechanical structure limitations in the prior art are solved, thereby meeting the high-standard polishing requirements of high-end customized tableware.

[0038] To better meet the high-standard polishing requirements of high-end customized tableware, in one embodiment, the multi-degree-of-freedom polishing equipment includes a device main body 1, a vertical polishing part 2 slidably arranged on the device main body 1, a horizontal polishing part 3, a first rocker part 4, and a second rocker part 5. A polishing head 9 is arranged on the horizontal polishing part 3. One end of the first rocker part 4 and one end of the second rocker part 5 are connected through a swing part 6. The swing part 6 is arranged on the device main body 1. The other end of the first rocker part 4 is connected to one end of the vertical polishing part 2. The horizontal polishing part 3 is slidably arranged on the other end of the vertical polishing part 2, and the horizontal polishing part 3 is connected to the other end of the second rocker part 5. The first rocker part 4 is connected with a driving part 10. The vertical polishing part 2 drives the horizontal polishing part 3 to move up and down synchronously in a reciprocating manner. The vertical polishing part 2 drives the swing part 6 to swing through the first rocker part 4. The swing part 6 drives the horizontal polishing part 3 to move horizontally in a reciprocating manner through the second rocker part 5, so that the multi-degree-of-freedom movement of the polishing head 9 adapts to the multi-directional polishing requirements of complex curved surfaces such as knives, forks, and spoons;

[0039] Among them, the polishing head 9 here can be adjusted at an angle of 30° - 60° with the horizontal plane, ensuring that while the polishing head 9 moves up, down, left, and right, it can also change the angle with the horizontal plane by 30° - 60°, so as to adapt to the corners and curved surfaces of knives, forks, and spoons, thereby achieving a comprehensive and uniform polishing effect; the angle adjustment of the polishing head 9 is realized through the hinge design of the mounting hole and the sliding plate, and after adjustment, it is fixed by bolts or fixtures. Among them, the angle fixation is an implicit technical feature, and those skilled in the art can implement it reasonably.

[0040] It should be noted that in this embodiment, the driving member 10 of the first rocker portion 4 enables the vertical polishing portion 2 to move up and down reciprocally, and the swing of the swing portion 6 enables the vertical polishing portion 2 to swing left and right. At the same time, the horizontal reciprocating motion of the horizontal polishing portion 3 and the cooperation of the second rocker portion 5 enable the polishing head 9 to move in the horizontal direction. These motions combined can achieve the flexible movement of the polishing head 9 in three-dimensional space. The first rocker portion 4 and the second rocker portion 5 are connected through the swing portion 6, enabling the swing portion 6 to precisely control the movements of the vertical polishing portion 2 and the horizontal polishing portion 3. The control of the driving member 10 can precisely adjust the swing amplitude and frequency of the rocker portion, thereby achieving precise control of the movement trajectory of the polishing head 9. Finally, through the ability of the polishing head 9 to adapt to complex curved surfaces, when polishing knives, forks, and spoons, pressure can be applied more evenly, improving the polishing quality. In addition, the synchronous movement of the vertical polishing portion 2 and the horizontal polishing portion 3 enables the polishing head 9 to cover all corners and curved surfaces of the item, thereby achieving a comprehensive and uniform polishing effect.

[0041] Since the polishing head 9 will generate vibrations during the polishing of knives, forks, and spoons, causing the polishing head 9 to shake, in order to prevent the polishing head 9 from shifting or shaking during vertical movement and ensure the linear accuracy of the up and down reciprocating movement, in an embodiment, the vertical polishing portion 2 includes a limit frame 21, a sliding rod 22, and a support rod 23. The two ends of the sliding rod 22 are perpendicularly connected to the support rod 23 and the limit frame 21 respectively. A slider 7 is provided on the equipment main body 1, and the sliding rod 22 is slidably arranged on the slider 7. Through the cooperation of the limit frame 21, the sliding rod 22, and the support rod 23, the sliding rod 22 slides on the slider 7 of the equipment main body 1 to form a stable vertical movement guide. The perpendicular connection between the limit frame 21 and the sliding rod 22 restricts the movement direction, preventing the polishing head 9 from shifting or shaking during vertical movement and ensuring the linear accuracy of the up and down reciprocating movement. The perpendicular connection between the support rod 23 and the sliding rod 22 forms a rigid frame, enhancing the mechanical structure strength and preventing deformation caused by polishing pressure. The sliding design of the sliding rod 22 on the slider 7 reduces the equipment volume and at the same time enables a large range of vertical movement to adapt to the polishing requirements of different sizes of tableware. In addition, high-precision vertical movement is achieved through mechanical constraints, providing a stable foundation for the subsequent superposition of horizontal and swing movements.

[0042] It is worth mentioning that since the targeted knife, fork and spoon tableware is for high-end customization, the precision requirements are higher than those of ordinary knife, fork and spoon tableware, and the error requirements for the complex curved surfaces of knives, forks and spoons are smaller. Therefore, when polishing, there will be a delay problem during the conversion between multiple degrees of freedom, which easily leads to a decrease in polishing precision. To solve this problem, in one embodiment, the first rocker part 4 includes a rotating wheel 41, a crank rod 42 and a first rocker 43 arranged in the limit frame 21. One end of the crank rod 42 is arranged at the eccentric position of the rotating wheel 41, and one end of the crank rod 42 is connected to the driving part 10. The other end of the crank rod 42 is hinged to one end of the first rocker 43, and the other end of the first rocker 43 is hinged to one end of the swinging part 6. The swinging part 6 is a swinging rod, and the center of the swinging rod is rotatably arranged on the equipment main body 1 through a rotating seat 8. The limit frame 21 is of a flat groove type structure, and the diameter of the rotating wheel 41 is the same as the width of the flat groove type structure limit frame 21. As Figure 3 shown, the driving part 10 here is a servo motor. The driving part 10 drives the rotating wheel 41 to rotate eccentrically in the limit frame 21 through the crank rod 42, and then transmits the power through the hinge connection between the first rocker 43 and the swinging part 6, forming the linkage between the up and down movement of the vertical polishing part 2 and the swinging part 6. Through the mechanical limit of the rotating wheel 41 and the rigid connection of the crank rod 42, the problem of transmission delay is avoided, and the real-time synchronization of multi-degree-of-freedom movement is ensured. In addition, the diameter of the rotating wheel 41 is the same as the width of the limit frame 21, aiming to ensure that the rotating wheel 41 rolls without clearance in the flat groove, reduce energy loss and vibration, and the position of the driving part is fixed on the equipment main body.

[0043] In addition, in order to ensure that the second rocker part 5 moves up and down synchronously with the first rocker part 4 while also being able to move stably in the horizontal direction, in one embodiment, the second rocker part 5 includes a second rocker 51, a connecting rod 52, and a sliding plate 53. The sliding plate 53 is slidably arranged on the support rod 23. One end of the connecting rod 52 is fixedly connected to the sliding plate 53, and the other end of the connecting rod 52 is hinged to one end of the second rocker 51. The other end of the second rocker 51 is hinged to the other end of the swinging part 6. A trapezoidal groove 231 is provided on the support rod 23. The sliding plate 53 has a trapezoidal structure, and the trapezoidal structure of the sliding plate 53 is slidably arranged in the trapezoidal groove 231. An installation hole is provided on the sliding plate 53, and the polishing head 9 is arranged in the installation hole. The polishing end of the polishing head 9 has an arc-shaped structure. The sliding plate 53 cooperates with the support rod 23 through the trapezoidal groove 231, and the connecting rod 52 is hinged to the second rocker 51, converting the swing of the swinging part 6 into the horizontal reciprocating motion of the horizontal polishing part 3. The trapezoidal structure of the sliding plate 53 matches the trapezoidal groove 231 of the support rod 23, providing self-locking guidance to prevent the polishing head 9 from deviating due to inertia during horizontal movement and ensuring the accuracy of the trajectory. The arc-shaped polishing end of the polishing head 9 and the design of the installation hole of the sliding plate 53 enable it to fit the concave and convex curved surfaces of the tableware during horizontal movement, avoiding polishing dead corners. The hinged design of the sliding plate 53 and the connecting rod 52 allows the polishing head 9 to adaptively fine-tune the angle during horizontal movement, combined with a PID controller to achieve uniform pressure distribution. Among them, the hinged clearance is controlled by precision machining, and the PID controller adjusts the pressure of the polishing head in real time through the driving part to compensate for mechanical clearance, and the fine-tuning is achieved through a control algorithm, independent of mechanical clearance.

[0044] The working principle and process of the present invention:

[0045] The multi-degree-of-freedom polishing device adopts a vertical polishing part 2, a horizontal polishing part 3, and a double-rocker linkage mechanism. Through the cooperation of the mechanical structure and the control algorithm, the polishing head 9 is driven to perform a composite motion in three-dimensional space. The vertical polishing part 2 consists of a limit frame 21, a sliding rod 22, and a support rod 23 to form a rigid frame. The sliding rod 22 slides vertically on the slider 7 of the equipment main body 1, restricting the movement direction and absorbing vibration to ensure the linear accuracy of the up and down movement of the polishing head 9. The first rocker part 4 drives the eccentric crank rod 42 through a servo motor, driving the rotating wheel 41 to roll without clearance in the flat groove-shaped limit frame 21, converting the rotational motion into the up and down reciprocation of the vertical polishing part 2 and the left and right swing of the swinging part 6. The second rocker part 5 converts the swing into a horizontal reciprocating motion through the self-locking guidance design of the trapezoidal groove 231 and the sliding plate 53. Combined with the 30° - 60° inclination angle adjustment of the polishing head 9, it covers the concave and convex curved surfaces of the tableware. The control system generates a multi-axis linkage trajectory based on the three-dimensional model of the tableware, and real-time corrects the motion parameters through the servo motor, harmonic reducer, and sensors, and dynamically adjusts the pressure and angle in cooperation with the PID controller to achieve adaptive polishing of complex curved surfaces.
